The flute is one of the woodwind instruments and has a blow hole on the side of the pipe. It is a significant solo as well as orchestral instrument and is widely used in music. For flutes with ring keys (open keys), the fingers close the hole in the key and operate the key. The advantage: the flutist feels the air speed in the fingertips and can correct it better. It requires a more precise finger technique and is beneficial for more precise flute playing. When the keys are closed, the fingers operate the keys and the tone hole is closed. The flute generates the vibrations by blowing over a blowing edge and not through the lips, as is the case with brass instruments.
